My cat turned 1 year old on memorial day , she also gave birth to 1 kitten on that day . She and the kitten were doing fine until about a week ago when she began to move him all over the house from odd place to place . Finally 2 days ago she almost completely stopped nursing him . This morning she smothered or crushed him to death we assume , when I went to get him to feed him again he was under her back hips and he was gone , it happened in matter of a few min . I had justed looked over less than 10 min. before and could see him moving around and he was as nosey as ever . Why did she do this ?
